South African Mopane

Mopane is one of the most underrated African timbers but it has many desirable characteristics.
As a tonewood it is similar to African blackwood, it is very hard, dense and extremely durable. Usually used for musical instruments, knife handles and high quality turned items like handmade pool and snooker cues.
Mopane is often sold in irregular lump form for use in fish tanks, where it's lack of buoyancy and high rot resistance make for a good reef. It is less widely available in workable blanks.
Mopane is a relatively safe exotic timber to work with, the normal precautions you would use for northern hemisphere species should be adequate.
